Driving yesterday, the check engine light came on and one code came up - 0161 (o2 sensor) came on. Re-set it and check engine light came on again today with a bunch of different codes (P1884, 0102, 0445, 0448, 0340, 0134, 0154). After i drove to lunch todya, I re-set those codes, and I got a the codes plus a couple additional codes ~0135, 0155. So now I have nine codes in total - -where do I begin -- how do begin to tackle this issue?

PS
Upon turning the ignition, the engine fires right up - but I have noticed today a slight -- slight - hesitation. Not sure if that suggestiive of anything either.

Many thanks!

Sounds like you might need some new O2 sensors. Fuses all ok? Check the O2 sensor connections. The front passenger one tends to get gunked up with oil.

 

Bro,

can d-code da code.

Put in codes from the Rave CD.

 

Started the day with 9 codes, got 3 more to sort out. They all have something to do with circuit issues.....what should I do?

I have noticed more and more hesitation/difficulty when starting the engine.

P0448 = EVAP system vent control circuit shorted

P0102 = Mass Airflow Circuit - Low Input

P0340 = Camshaft position sensor circuit malfunction Open/short circuit to vehicle supply or earth.

 

I'm going through something similar. Changed the camshaft position sensor, crankshaft position sensor, and the mAF. No change. I will start a thread once I get a chance, but I think I have some frayed wires somewhere.
